I regularly see people ask totally uninformed or non-believable people questions and get answers that they believe. This is often worse than having no answers at all.
Don't make that mistake. You need to think through who the right people are. If you're in doubt about someone’s believability, find out.
The same is true for you: If someone asks you a question, think first whether you’re the right person to answer it. If you're not believable, you probably shouldn't have an opinion about what they're asking, let alone share it.
Be sure to direct your comments or questions to the believable Responsible Party or Parties for the issues you want to discuss. Feel free to include others if you think that their input is relevant, while recognizing that the decision will ultimately rest with whoever is responsible for it.
